The 'America's Got Talent' presenter and his wife have ended their marriage, but Nick, 33, has taken to Twitter to express his love and gratitude to the mother of his twins, daughter Monroe and son Moroccan, for everything she has brought to his life.

He posted: ''I love @MariahCarey and that will never change!!! (sic)''

Nick also defended Mariah, 44, insisting the criticism she has received in the wake of their separation is completely uncalled for.

He added in a series of tweets: ''What infuriates me most is to hear people slander @MariahCarey . I will forever be in debted to her for blessing me with our children ... I will always love her unconditionally for this and so much more. @MariahCarey is an amazing Mother and I trust her wholeheartedly... (sic)''

Nick also spoke out to attack some of the rumours that have circulated since their break-up and admits he has been angered by some of things he has read.

He tweeted: ''Because my family & I haven't been forthcoming with personal information, people are quick to paint negative pictures and spread rumours.

''For the record I NEVER have, nor will I make a statement regarding my marriage. (sic)''

Nick added: ''If the media wants to portray me as the Bad guy that's fine ... But it is unfair to drag innocent people into the equation ... Others have lives, families, and careers and for the media to slander them is down right evil and illegal ... I apologize to anyone who's gotten caught up in this unwarranted drama.''
